Gamuda, through DT Instructure’s 50:50 joint venture (JV) with Samsung C&T Corporation, called TasVic Greenlink, is delivering major infrastructure works for Stage 1 of the Marinus Link project by the Marinus Link Pty Ltd, a jointly owned entity among the Commonwealth of Australia, the State of Tasmania and the State of Victoria.

Marinus Link stands as a project of profound national significance connecting Tasmania and Victoria in Australia. Far more than just a sequence of cables, it is a sophisticated undersea and underground bridge, designed to unite these two regions through a shared flow of electricity and data.

Stage 1 of the Marinus Link Balance of Works package includes major onshore civil works across several sites to support the installation of underground High Voltage Direct Current (HVDC) cables, the construction of new converter stations in Tasmania and Victoria and a dedicated communications building for the project’s telecommunications and control systems.

The works include excavation, trenching and site preparation to support the installation of around 90 km of underground HVDC land cables. This also involves cable jointing and termination, as well as the protection and management of existing services, all carried out in line with strict technical and safety requirements.

Throughout construction, comprehensive environmental and safety measures are being implemented to meet regulatory approvals and ensure compliance with heritage, cultural heritage and ecological obligations, as well as workplace health and safety standards.

Once fully operational, Marinus Link will raise electricity transfer capability to 1,500 MW and increase data capacity by 150 times. The project is expected to unlock new renewable energy investment and support thousands of construction jobs, bringing significant economic opportunities to North West Tasmania, the Latrobe Valley, Gippsland and South Gippsland.

Stage 1 of Marinus Link is expected to commenced in 2026, with completion scheduled for 2030.
